` Claims.

This invention relates to improvements in frost- Jr'oof hydrants,drinking fountains, wash sinks and other like water service apparatus ofthat type embodying a stand pipe having a discharge .nozzle andavalvemovable to a position for admitting water from a source of supplyto the stand pipe for discharge through the nozzle and to aposition forcutting offv the supply of water to the stand, pipe and connecting thestandp-ipe with a drain outlet for the drainage ,of` Water from thestandpipe after each water supply action. Ihe combinedwater supply and drain`,valve referred to yis carriedy by a rod or stem ,whichl ex tends.upwardly through the stand pipe and is adapted` to beraised by ahandleor operating device to open the valve for a water supply action and tobe lowered to return the valve to normally closed position in which itcuts off the ,supply of water andsimultaneously connects, the stand pipewith the drain outlet. The movement of the valve to openposition in thistype vvof apparatus results in a full or maximum flow of water throughthe nozzle, no provision being made for securing a graduated orregulatedflow. It is desirablein some uses of a frostproof hydrant tosecurea graduated or regulated dis.- charge of the water withoutinterferingwith the normal operation of -the hydrant for securing lafull flow action and also without endangering its frostproof properties.i v

One object of my invention is to provide aconstruction of frostproofhydrant whereby .a full ilow or partial or regulated flow may be securedat will.

Another object of my inventionis. to provide means wherebythevalvemechanism may be operated in the usual manner for a full iiowaction and in a different manner for a desired reduced ,l flow action.

Still another object of. the invention is to provide a means whereby anordinary hydrant valve mechanism may be readily .modified to 4secure aregulated ilow action without material .departure from a commonly usedfrostproof valve structure .1 Siiflietian, Combinati@ .andarrnementotparts,

Referring now more particularly to the drawings, .I designates a standpipe which is connected atitsflowery end .with a water service or supplykpipe 2 and is. .provided near its upper 'end with 35 a .water dischargeoutlet,herein shown in theiorr'n of a discharge nozzle 3. Adjacentitslower end, and at .a suitable elevation above thel pipe l,lthe standpipel is also provided-with anioutlet 4 ci. for connection with adrainpipe-S. The drain 40 outlet.4 communicates with-the upper portionof a part or section E .of the*y pipe l 4which serves as a valvechamber, in which is, arranged a vertically movable combined waterinletand drain valve l.. This valve 1 comprises a lowerv valve 45 member8 controlling the inlet of'water from the pipe .2 and van uppervalve-member 9 controlling the. drain'outlet. 4. The valve member 9 ishol, low or of openworkconstruction and provided above yand below theplane of its seat surface lwith 50 ports l0 and Ilv to allow watertoilow between the pipel ,above .the level of the drain .of the'drainvalve andthedrain .outlet .or Vthewaterinlet 2 in-,the differentpositions of the valve members 8 and 9. 55

and fully openedpositions respec- 15` 'I'he valve 1 is connected to thelower end of the main section of a rod or stem I2 extending upwardlythrough the pipe I to a point substantially in line with the lowerend ofan outlet chamber I3 attached to the upper end of the pipe I, whichchamber serves as an auxiliary valve chamber and has formed thereon orattached thereto the discharge nozzle 3. 'I'he upper end of this chamberI3, which projects above the nozzle, is closed by a stuffing box I4provided with a gland or followerfl clamping suitable packing I6 inplace. Anf up'per or operating rod section I1 is disposed Within theoutlet chamber and extends at its upper end outwardly through thestuffing box. The lower end of thisrodsection I1 is connected to theupper end of the'main rod I2 by a threaded sleeve coupling I3, while theupper, outwardly projecting Y endk of said rodV section I1 carries anoperating handle or lever I9, whereby the rod as a whole may beraisedand lowered to operate the valve 1. A coiled spring 20 disposed aboutthe rod section I1 between the coupling I8 and the top of the stuffingbox or a thimble 2| bearing thereonv serves to hold the rod normallydepressed and the: valve 1 in water cut off position. Thehandle or leverI9y has a forked or slotted headporti'on 22 receiving a cap 23 threadedonto the upper end of `the rod section I1, through lwhich rod section,cap and the side walls ofthe slot of th'ef head 22 passes a pin or bolt24 pivotally mounting the handle on the upper end of the valve rod. VThehead 22 is so pivoted or shaped for engagement with the gland I as toserve as a lifting cam operating when the handle I9 is swung on itspivot from a normally vertical position to a horizontal position to liftthe rod against the resistance of the spring 20 and thereby raisethevalve-1 fromwater 'cut out to water let on position, in which action theupper end of the rod section `I1 andcap 23 move in the slot of the head22. In the upward movement of the valve 1 the drain outlet 4 is closedand communication between the stand pipe and supply pipe 2 establishedfor the flow of water in full volume to the nozzle '3. When the handleI9 is shiftedrback toits normally vertical position the rod isldepressed by the action of the spring 20, the valve 1 being therebyreturned to normal position to cut off the flow of water from the pipe 2and to open communication between'the stand pipe and drain outlet 4for'the discharge of all residual Water remaining in the stand pipeabove the valve 1. In practice the Water supply connections to thestandpipe are arranged below the frost line, and this drainage'actionensures that no residual water from a supply action is `allowed to`remain yin the stand pipe to freeze in freezing weather.

,A disadvantagel applying'to water service apparatus of this .characteris that when the valve 1 is opened a fullvolume dischargeof water fromthe nozzle 3` always occurs. At times and Ain certain uses of theapparatus, as when it is desired tosecure the discharge of water insmall or varying volume, this is objectionable not only on account ofthe Waste of water but for many other obvious reasons. yIn order toavoid this objection I provide vmeans whereby after opening of the valve1 the discharge of lwater from vthe nozzle 3 may be reduced andgraduatively controlled', whichl means is of such vconstruction that itdoes not interfere with or impair the'frostproof control action of thevalve mechanism. To this end I provide auxiliary valve means operativeby rotation of they valve rod or stem when the valve 1 is open forcontrolling the discharge of Water through the nozzle 3.

In Figs. 1 to 6, inclusive, I have shown one form of auxiliary valvemeans for this purpose in which the chamber I3 is provided with aprojection or inwardly extending offset 25 and a port 26 dened thereby,which port connects said chamber with the inlet end of the nozzle. Forcooperation with said port an auxiliary valve is provided comprisingwing like segmental shaped flanges 21 on the 'coupling I8. These flangesare so shaped as to form between them flow passages 28; and each flange21 is so accurately formed for coaction with the port 26 that when,disposed beneath said port l and turned in either direction it will forma passage of variable size between the chamber and port to graduativelycontrol the flow of water therefrom to the nozzle, while when eitherpassage 28 is'disposed in register with the port a full ow of watertothe nozzle is allowed. In the normal position of the parts one of thevalve wings is centrally disposed beneath the port 26 and spaced such adistance therefrom that when the handle I9 is operated to lift the valve1 to open position the said valve wing vwill bebrought close to but notin full closing relation to the port. By this means the ow of water tothe nozzle willbe reduced to a minimum service rdegree but not entirelycut off. By rotation of the handle I9, in the horizontal positionjtowhich it has been moved in lifting the valve 1, the` valveA stem may beturned to the right or left to adjust the acting valve wing to vary theextent of its obstructing surface relative to the port 26, whereby thedischarge of water through the nozzle may Vbe graduatively regulated asdesired notwithstandgagement therewith of 'a flanged clampingring 29threaded onto the casing andwherebyv the stuffing box is held fromoutward displacement'.

This stuffing box conforms generally, so far as its packing features areconcerned, with the structure shown in Figs. I to 6, inclusive,`and itssimilar parts are correspondingly numbered. This box I4a, however, isformed with a depending shell30 provided in its side with a port 3lfacing the nozzle and having an annular bottom wall 32 formed with setsof valve ports 33. The coupling member Ia in this construction has acircular flange or valve disk 34 provided with arcuate slots 35 forcooperation with the sets of ports 33 to secure a graduative dischargeaction. The shell 30 may be provided with a spline or key projection 36to engage a seat groove 31 in the casing for holding the shell fromrotationand ensuring accurate positioning of the valve ports 33. The

` operation with this construction is the same as that described withrespect to the construction shown in Figs. 1 to 6, inclusive, for thepurpose of obtaining a graduative discharge of the water.

In both forms of the auxiliary valve means disclosed the constructionand range of movement of the auxiliary valve member on the rodtoward thestationary valve member inthe auxiliary valve casing i's'such that inthe maximum to the nozzle as long as valve 'I is open and in the fullestow obstructing position of the auxiliary valve. Thus in the event thatthe handle should not be returned to normal position after a dischargeaction, that fact will .be vvisually indicated by the flow of a smallamount of water from the nozzle, ensuring attention being given to cutoil the flow by returning valve 'I to closed position for a drain actionand to'prevent freezing of the hydrant during freezing'weather. Myinvention thus provides in addition to its advantageous featuresdescribed a simple safeguard against the valve 'l being left openthrough oversight after use of the hydrant, whereby the frostproofproperty of the hydrantrstructure is maintained and preserved.

From the foregoing description,v taken in connection with'the drawings,the construction, mode of operation and advantages-of my invention willbe readily understood, and it-will be seen that the invention provides afrostproof hydrant or other frostproof water service apparatus wherebyeither a full or graduative discharge of water from the discharge nozzlemay be secured at will and by the provision of a simple and eiilcienttype of means for the purpose. vAlso it will be seen that the inventionprovides auxiliary valve means for a graduative water discharge actionwhich may be employed without interfering with the normal operation oithe hydrant and without endangering its frostproof properties. It willfurther be seen that the invention provides auxiliary means for agraduative flow discharge action which may be applied to and employed inconjunction with the parts of an ordinary hydrant valve mechanism andwithout material departure from approved types-of frostproof hydrant orlike water service structure. While the construction is such that thecustomary return of the operating handle to normal position after awater supplying action ensures that the main valve will be returned towater cut off and drain position, the invention further safeguards theapparatus against liability of freezing'by providing a means forindicatingwhether or not the main valve has been returned to cut offposition, thus enabling measures to be taken to prevent freezing in casethat through carelessness or inattention on the part 'of kthe operatorthe operating handle should be left in valve opening position.

It will, of course, be understood that while I have shown certainembodiments of myvinvention for purposes of exemplication, changes inthe form, details of construction and arrangement of parts may be madewithin the scope of the l appended claims without departing from thespirit or sacrificing any of the advantages of the invention.
